1.is folder structure ideal folder structure?

there no ideal structure. structure depends on type of application, size, development methodology. better create project hold domain entities , services.

2.is idea creating entity data model each module in application ? (eg:ads,categories)

this depends on size of application , boundaries in business logic(eg: 1 context sales logic , security). in case single context enough.
